Artur Boruc can't wait to hang up his gloves for good after a farewell date with Celtic.
The Polish goalkeeper will end his career at the age of 42 with a match against Postecoglou's side on July 20.
It's a fitting tribute sign-off the former Hoops hero, who won three league titles in Glasgow and starred in the Champions League, that he will draw a line under his stunning career with a glory match between his native Legia Warsaw and adopted side Celtic.
And he has revealed that he plans to turn his back on the game for good.
Boruc said: "I will play the last game in my career in the colours of Legia against Celtic, whom I also support and are a club very close to me, where I spent great years.
"The match is a very nice initiative on the part of Legia, a really good ending to my adventure. I am very happy with this match.
"Unfortunately, my advancing years and health doesn't allow me to represent the colours of Legia Warsaw at an appropriate level. So I decided to stop.
"My health will not allow me to continue. I feel more and more ailments and it this season was probably one of the first moments when I got scared of what might happen in my life in the future. I started to pay a little less attention to football and a little more to health.
"Ultimately, I think that I will not live in Poland, my wife and I think about the United States - perhaps sunny California, to have warm and beautiful weather for 300 days a year.
"I have no idea what I will do in the future. Football has been my life. I have never really thought about it.
"I read a story in Poland that said I was going to go into scouting when I retire. Where could I be a scout? Maybe in the bars of Warsaw to scout for the best beer!
"No, I don't want to stay in football."
